A prosthetic mesh and method of use in surgical methods for closure of abdominal incisions and prosthetics for repair of ventral hernias. The mesh provides for a new prosthetic that can be used for closure of laparotomy incisions, in patients at high risk for hernia formation, and in the repair of existing ventral hernias. The mesh utilizes existing multi laminar technology for intra peritoneal mesh, and fashions it in the shape of an intact Rectus Sheath. The mesh matrix can be made of any of the various absorbable or permanent polymer filaments that are woven or knitted into a scaffold for added strength to the abdominal wall closure during the healing phase, and for delivery of bio active substances that contribute to a biochemical milieu that contributes to favorable healing. A permanent non absorbable prosthesis will be desirable in certain circumstances and for particular patients, a slowly dissolving mesh would be ideal in most cases. The absorption of the prosthesis must be slow, approximately one to two years, thus giving enough time to preserve support for the healing abdominal wall repair, as this is the period of time over which most incisional hernias present.

Formulations of the invention may be used for the treatment of numerous conditions including for example, treatment of peripheral arteriopathies, treatment of acute renal insufficiency, treatment of acute myocardial ischemia, and treatment and prevention of sinusoidal obstruction syndrome or VOD.

Sepsis is a complex, incompletely understood and often fatal disorder, typically accompanied by hypotension, that is considered to represent a dysregulated host response to an infection. Neurotensin (NT) is 13-amino-acid peptide that, among its multiple effects, induces hypotension. It is shown herein that plasma concentrations of NT are increased in humans with sepsis and in mice after caecal ligation and puncture (CLP), a model of sepsis. Mast cells can degrade NT through neurotensin receptor 1- and neurolysin-dependent mechanisms, diminishing the hypotensive effects of NT, reducing intraperitoneal NT concentrations, and improving survival. These findings show that mast cells can regulate NT concentrations, and identify NT as a biomarker and therapeutic target in sepsis.
